I have a MN5048DIY inverter that is giving a positive voltage on the inverters neutral terminal, which is completely disconnected from any loads; it is just the batteries, PV panels, and the inverter. For some reason, I'm getting back feeding or something on my neutral side. Any help would greatly be appreciated. Thanks...
Are you saying you get voltage reading between neutral and ground ?

And how much voltage are you reading ? Is it the whole battery voltage or just a little ?
It may be some high impedance leakage ? If that is the case, then you could use resistors to measure the impact of this leakage.
Does the inverter appear to work OK otherwise ?

Neutral floats in the inverter and depends on you to make a neutral to ground bond some where in the AC system, Without that bond neutral will have voltage readings to ground as it is floating.
